March 24, 2014 — ProTom International Inc has received 510(k) clearance for its Radiance 330 Proton Therapy System. The Radiance 330 is a compact, modular and more affordable proton beam delivery system for the treatment of patients with cancer. The system delivers extremely focused, conformal, scanned proton beams that destroy tumors while sparing nearby healthy tissue and anatomical structures.
The system’s modular design easily accommodates the buyer’s preferences for 3-D imaging solutions and treatment planning software through industry-standard interfaces. The compact accelerator can be installed within an interior vault space of approximately 20-by-30 feet and requires up to 40 percent less radiation shielding than many other systems on the market today. The Radiance 330 can be configured using its single, energy-efficient synchrotron to operate a single or multiple treatment room facility; treatment rooms can be equipped with isocentric gantries or as fixed-beam lines with one or more ports.
